Trade in you can expect about 24000-26000 depending on condition and the dealer. Assuming that your retail is 33000. That is about 70%, from retail.

Outright sell is a little trickier, there is so much competition for you so you have to give the buyer a reason to buy your camper over the dealer or the next guy. Typically price is going to determine that, but accessories & aftermarket add ons help too!

I have a similar camper and looked into trading it in this summer. The dealership started out offering me around $22k for the trade. I found similar numbers for retail as above. Mine is a 2014 that I haven't quite had for two years. Good luck trying to sell it.
